So I dropped my 2016 S off for service and am driving a loaner this weekend. I noticed a few things of course and others who have had new/old S know many of these observations. First thing this car is a VERY early S , a 2012 with a VIN# of XXX01272. I believe that makes it just under the first 1300 model S's made? It is an 85kwh, No "P" or "D". It only has 20,200 miles so maybe it has always been a service center car and it is in really good condition, surprisingly. A few scuff marks here and there that I made sure were noted before I drove away Couple observations: It is the dark green color that looks black at certain angles. Not my thing but a very nice color option. I never liked the front grill look. Tesla +1 for improving Headlights/tailights Tesla +1 for improving Slightly quieter to my 2016 if only because it is RWD. No low speed front motor whine. No Pano roof. I miss it. Feels more constricted. IMHO Headroom in rear is really low. The dashboard trim is fading and scuffed. Appears lower quality than the current trim options. Tesla +1 for improving The interior headliner is hard plastic. Today it is a nice soft velour type feel. Tesla +1 for improving The leather seats are uncomfortable. I remember reading on this forum about the early seats being thin. Tesla +1 for improving The regeneration is so much less aggressive but works well and I like it better at highway speeds than my current regen. Tesla : No points for or against but this is opinion. Probably deserves a +1 for better regen. today but..... Creep: This car creeps a little bit and the "Creep" mode is off. Also no "HOLD" function. Tesla +1 for improving Have to remember to hold the brake at traffic lights for even the slightest road grade. No Autopilot! Ahhhhhhhhhhhhhh! I have to drive ALL weekend! Feels like a dinosaur I keep flipping the cruise control stalk for turn signals. They were opposite then apparently. Gear shifter stalk is also different. Were these early stalks also from Mercedes? Tesla +1 for improving No middle console, just a big open space. Tesla +1 for improving The middle arm rest stitching is right where I lean my arm and "scratchy" Tesla +1 for improving If the early adopters can add to this i would be very interested in how they have improved upon some subtle points. And hey, early adopters: Thank you! I am enjoying getting a chance to drive one of the first made. Despite some faults that have been improved upon and some maybe still needed, it is a great car that just needed refinement. And little by little that refinement is clear to see. I think Tesla still has more improvements for the S, including quality control and an interior "plush" feel that is missing IMHO. I can see why car magazines and CR rated this car so highly almost 5 years ago. We can all argue the merits and negatives, beat 'em like a dead horse here but remember the 2012 Model S was a game changer.
